Application tiled .Tune 22, 1915. Serial No. 35,614.

To all whom it may concern Be it known that ll, Heier-rr SAWAMURA, a subject of the Emperor of Japan, residing at N ew York, in the county of New York and State of New York, have invented new and useful improvements in Pens, of which the following is a specification.

rlhis invention relates to pen points and it consists in the novel features hereinafter described and claimed.

An object of the invention is to provide upon a pen point a pocket located along the median longitudinal dimension of the pen and adapted to contain a supply of ink to be fed to the nibs of the pen.

Another object of the invention is to provvide upon the pen a dam or partial barrier located at the lower end 0f the said pocket, and adapted to hold the major portion of the ink back in the pocket but which is so arranged as to permit a sufficient quantity of the ink to flow to the nibs when the pen is in use.

ln the accompanying drawing z-Figure l is a top plan view of the pen. Fig. 2 is an under plan view of the same. lFig. 3 is a transverse sectional View of the pen cut on the line 3 3 of Fig. l. Fig. 4 is a similar view cut on the line 4 4 of Fig. l.

The body of the pen 1 is of the usual contour or configuration and the said pen is provided at its pointed end with an incision 2 disposed along its median longitudinal line, and which divides the pointed end of the pen into nilos 3. The pen l is further provided with incisions 4, which are disposed at the opposite sides of the incision 2 and at equal angles with relation to the same. At their inner ends the incisions 4 communicate with an opening 5 made by removing part of the material of the body of the pen at a point between the ends of the incision 2. At their outer ends, the incisions 4 communicate with openings G provided at the opposite side portions of the body of the pen 1. rl`he material of the body of the pen which is removed from the openings G, is bent back, forming tongues 7 which slightly overlap each other at their free ends, as best shown in Fig. 3 of the drawing.

At the upper end of the incision 2 the body of the pen is provided with a depres sion which constitutes a pocket 8. This pocket is elongated and its long dimension is disposed in a line with the median longitudinal dimension of the body of the pen l.,

rllhe tongues?v are located at the lower end of the pocket 8 and bridge the same, and the inner ends of the tongues are slightly spaced above the lower edge of the pocket as best shown in Fig. 3.

When the pen, as shown and described, is dipped in ink, a quantity of the ink enters the pocket 8 and is retained therein by the overlapping tongues 7. Also globules of ink are retained in the openings 5 and 6. When the pen is used for writing purposes the ink may gravitate down along the incision 2 from the pocket and the said open ings and thus it is spread to the ends of the nibs. By reason of the fact that the tongues 7 are spaced slightly above the lower edge of the pocket 8, the said tongues hold back the major quantity of ink in the said pocket, but permit a suliicient amount thereof to flow down along the incision 2 to properly supply the points of the nibs without iooding or causing the ink to blot upon the writing material.

From the above description taken in conjunction with the accompanying drawing it will be seen that a pen of the usual contour or design is provided and'that the pen is further provided with means for retaining or storing for use, a sufficient quantity of ink to materially prolong the use of the pen for writing purposes without necessitating frequency in dipping the same in ink. rlhe ink is not only stored in the pocket 8 but is also retained in the openings 5 and 6 in minute quantities, and therefore the incision 2 is fed from several different sources and in the event that the ink in one source of supply should become thick or hardened, the ink which is permitted to flow along the incision 2 may pass bv capillary attraction to the said source and loosen or dissolve the hardened ink to such an extent as to permit the same to fiow down along the incision 2 while the pen is used for writing purposes.

Having described the invention, what is claimed is:-

1. A peu comprising a body having at its pointed end an incision which divides the same into nibs, a pocket provided at the upper end of the incision and overlapping tongues provided at the lower end of the pocket and spaced slightly above the upper edge of the same.

2. A pen comprising a body havingr at its pointed end an incision which divides the same into nibs, a pocket provided at the upe per end of the incision, tongues cut froinlthe materiel of the body of the pen and bent back :ind overlapping each other at vtheir inner ends and spaced slightly above the lower edge of the pocket. W

3. A pen comprising a body provided at its pointed e'nd with an incision which divides the saine into nibs, other incisions located at the opposite sides of the first mentioned incision and communicating at their inner ends with the same, openings provided at the opposite side portions of the pen body with which the last mentioned incisions com- Inuniczite, a pocket formed in the body of the pen at the upper end oi the iirst 1nentioned incision, the material from the said openings being bent back and constituting tongues which overlap each other :it their inner ends and which are spaced slightly above the lower edge of the pocket.

In testimony whereof I, aiiix 1ny signature in presence of two witnesses.
